Hey,
We're looking into this and were hoping you could lend a bit more information.
*A screenshot of the error message you receive would be absolutely lovely.
* What kind of network were you using? For example, are you on your home wifi network, were you on Starbucks wifi, or were you accessing via a cellular network?
*Are you experiencing this issue on other secured sites (Paypal for example?)
If you could send this information to our Support team with 'Mobile, SSL certificate' in the subject line it'd be much appreciated.
